IMPROVEMENT IKN BUFFING-NIACHINES FORKBOOTS AND SHOES'.

Specification forming part of Letters Patent No. 22 1,286, dated November 4, 1879; application filed September 3, 1879.

To all whom it may concern:

Be it known that I, J oHN L. Corr, of Rochester, in the county of Stratford and State of New Hampshire, have invented a new and Improved Bufting-Maehine for Boots and Shoes, of which the following isa specification.

My improvements relate to machines for sandpaperin g the soles of boots and shoes 5 and they consistin a swinging standard hung upon adriving-shaft, and extending over the bench, to the upper end of which is jointed an arm that carries the sandpapering-roll, and is capable of movement to bring the roll to the positions required. The roll is driven, by pulleys and belts, from an intermediate cone-pulley on the standard, which is driven by a belt from the drivin g-shaft.

The construction will be more particularly described with reference to the accompanying drawings, and the invention pointed out in the claims.

In the drawings, Figure lis a sectional plan View of the machine as applied to a bench. Fig. 2 is a vertical longitudinal section of the same.

Similar letters of reference indicate corresponding parts.

A is a section of a work-bench fitted with a rack, a, for lasts and tools, and a finishingpost and headblock, b, these parts being as usual.

Upon the oor beneath the bench, in suitable bearings, is the driving-shaft c, provided with a fast and loose pulley, and carrying the drivin g-pulley c. To the shaft c is hung loosely a standard, d, which extends upward through a slot in bench A, the slot being near one end of the bench, and about midway of its width. The upper end of standard d is forked, as shown, and is fitted with a shaft, d. On the shaft df, in the fork of standard d, is iixed a cone-pulley, c, from which a belt passes to pulley c on the driving-shaft.

The stan'dard d is made in two parts, united by a dowel-joint, and adjusted by a nut and screw, f, whereby the length of standard d maybe varied and the upper part of the standard may turn axially upon as well as swing with the lowerlportion.

At the upper end of standard d, on shaft d',

an arm, g, is hung so as to swing vertically on shaft d as an axis, this connection forming a knuckle-joint. The arm g carries at its outer end a rectangular frame, h, that is hung, as hereinafter described, so as to have universal movement, and carries the sandpapering-roll l1' in suitable journals at its outer end.

The side bars, k, of frame h swing on the end piece, Z, which is fitted to swivel on arm g. 1n the bars his fitted a cross-shaft, my, that carries a pulley, m', from which a belt passes to the cone-pulley c, and also carries, at its outer end, pulleys a a, that are connected by belts with pulleys t t" on the shaft of the sandpapering-roll vB y this construction the frame h can be moved to the position required for applying the sandpaperingroll, and the roll at the same time will be continuously revolved.

The frame h is tted with a handle, o, pro= jecting from a rigid crossbar, p, to assist in the manipulation of the frame.

The machine is to be driven by power or by a oot-treadle, and when driven by power a suitable lever will be fitted for operation by the workman to throw the machine in and out of action.

or boot that is to be buffed and sandpapered upon the head-block of post b, starts the machine, and, by means of the handle o, brings the roll fi down upon thefsole and manipulates it as required.

The connectionsdescribed permit the roll to be turned in any required direction, and the work may be done thoroughly and rapidly, and without dust from the pumice-stone that is required in hand-work.

1 do not limit myself to the connections exactly as described, nor to the manner of sustaining the machine.

The frame may be hung to the wall or ceiling above the bench, the arm g in that case hanging downward and fitted with suitable connections for obtaining the necessary movements.

The sandpapering or buiiing roll is a rigid roller, covered with a surface of sandpaper or cording to the work to be done.

lIn operation, the workman places the shoe.

other abrading material, more or less fine, ac-A L', end piece l, cross-bury), and handle o, fitted with the shaft m and roll i, and jointed to the swinging arm g, substantially as and for the purposes described.
